Getting ERROR Connection not open CLOSED when composing Futures using vertx-jooq-classic-reactive: 5.0.1

Setting up PostgreSQL in GitLab CI

Unable to set up PostgreSQL in Travis CI because before_script doesn't work

QUESTION

Getting ERROR Connection not open CLOSED when composing Futures using vertx-jooq-classic-reactive: 5.0.1

Asked 2020-May-02 at 08:03

I have an issue when multiple Futures are being composed in order to perform update Book table and insert/delete certain rows in intermediate tables _Category_Book_ and _Author_Book_ since Book is connected with Many-To-Many relationship with Author and Category. Error message that I get in console is:

ERROR com.ns.vertx.pg.BookJooqQueries - Error, something failed in deleteCategoryBookFuture.compose(..)! Cause: io.vertx.core.VertxException: Connection not open CLOSED

Also, I am using mixture of DAO instances and execute() method on instance of ReactiveClassicGenericQueryExecutor class. This is repo link to my class where I am getting this error and this is HttpVerticle where routes, DAOs and other configuration is taking place for my RESTful web services.

I don't know if there is a possibility that I've "over-composed" Future instances and that's what's causing this error, but as I understood composition is used when certain operations (Insert/Delete/Update) need to be performed in sequential order and all have to succeeded.

Libraries I am using:
Vert.x version: 3.8.2
vertx-jooq-classic-reactive: 5.0.1
postgresql: 42.2.2 (Postgres DB is version 11.7 on my machine)

NOTE: I have these changes made in my book_CRUD branch, not to be mistaken with master (as I don't want to merge these not fully functional changes).

I've (to be more honest @jklingsporn) managed to find a solution a solution to fix issue. Problem was that (as much as I understood) is to compose not Future instances, but there right-hand side values (that is method invocations). For example, I had my code written like this:

QUESTION

Setting up PostgreSQL in GitLab CI

Asked 2017-Apr-22 at 19:03

I am trying to set up a CI runner at GitLab.com and I would like to use it to run tests that need a PostgreSQL database connection. The documentation of CI + PostgreSQL seems to be overly simple and it seems to tell that once the connection information is provided the database setup is done. I probably misunderstand the documentation as I fail to create the database. My gitlab-ci.yml looks like this

In GitLab CI your job is running within a docker container. Postgres is therefore NOT running on localhost, but on a host that is reachable on "postgres" (the service name is the server name that resolves to the IP you can use to reach the DB).

It looks like CI sets an ENV variable called "CI" so that you can switch you DB connection for test in CI from "localhost:5432" to "postgres:5432" in case you are running within the GitLab CI environment.
